I have been seeing these around my tank, above the waterline! They move and duplicate if cut in half. They do NOT have a triangle head. If they get in the water they are light pink and they squirm around.
There are not many around the tank. Just a couple above the waterline, and on the lid - that is, if I see them I get them out as soon as possible! Are they going to kill my fish? I have 6 flame tetras, 2 apple mystery snails and 2 bottom feeders.
Also, there’s a over growth of green algae, just splotches of green on the walls, I have a scrubber, but it keeps growing. Help me please!
